Among the present invention, described cylindrical cam has spiralling cam groove face, and this cam groove face is vertical profile between peak and minimum point.Like this, axle can vertically be fallen minimum point after arriving peak, makes workbench produce up-down vibration.
Among the present invention, described support steel cylinder inwall is provided with liner; As further improvement, this liner is the PVC liner.Adopt the benefit of this liner to be effectively to reduce the friction force of axle when moving up and down, not only alleviated the wearing and tearing of axle, and effectively reduced energy consumption.
Among the present invention, described hub diameter size is can fall into steel bowl and to realize suitable to effective boil down to of ring-spring.This structure can avoid runner directly to fall the minimum point of cam groove face, thereby prevents because both rigid collision cause the damage of equipment.
Among the present invention, the end face of described workbench is installed fiberboard; As further improvement, described fiberboard adopts screw to be installed in the end face of workbench.The main effect of this fiberboard is that the table top that can prevent workbench is directly corroded, and has prolonged the serviceable life of workbench.
Among the present invention, the bottom surface of described workbench is provided with reinforcement.Reinforcement is the rib shape projection from center radiation, can strengthen the reliability of workbench greatly.
Among the present invention, described axle be equipped with can regulating shaft length retractor device.This retractor device can be regulated shaft length, thereby can realize that the distance of pair roller and cam groove face minimum point is regulated and control, to avoid rigid collision between the two when the wheel hub compression spring.
Among the present invention, described workbench is provided with spud pile, and this spud pile inserts in the dowel hole of steel bowl outer wall setting.This structure can prevent the workbench rotation.
Owing to adopted above technical scheme, the present invention has following beneficial effect:
The present invention is simple in structure, simulates the vibrations that fireworks are subjected to by the up-down vibration that realizes workbench in handling process, so that the fireworks Transport Safety is made scientific and reasonable testing evaluation.
